The IFC board is the central microprocessor that orchestrates every heating sequence: it energizes the inducer, proves the pressure switch, fires the hot surface igniter, monitors the flame sensor, and commands the blower motor through every stage of operation. When this board fails, symptoms range from a complete no-heat lockout and constant fault-code flashing to erratic blower behavior, ignition attempts with no flame, or a furnace that starts briefly then shuts down without completing a heat cycle.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part Numbers:\u003c\/strong\u003e HK42FZ016 (original) | 325878-751 (current OEM kit replacement) | Cross-references: CEBD431012-01A, CEPL1311012-01, 1012-940-M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eElectrical Specifications:\u003c\/strong\u003e Input voltage 98–132 VAC @ 60 Hz | Igniter output: 5A @ 120 VAC | Cool blower: 30A, 2 HP, 240 VAC | Heat blower: 5A, 1\/2 HP, 240 VAC | Inducer motor: 4A FLA \/ 8.0 LRA @ 120 VAC | Gas valve: 24 VAC | Onboard diagnostic LED fault codes for rapid troubleshooting\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs. Generic:\u003c\/strong\u003e This OEM board ships with factory-matched firmware, plug-and-play connector harnesses, and the exact diagnostic LED fault-code label required by Carrier service documentation.
